PSA: Memory leaks, using Hibernate and Suspend all of the time - it's good to reboot.

[VirtualLarry]

Every month or so, at least. I do it every time there's a major Firefox / Waterfox update, usually.

Even after shutting all of my programs down, my Commit Charge in Win7 was over 2GB, for some reason. Seemed kind of high to me. So, I rebooted. Now WITH my programs open, I'm getting similar Commit Charge numbers.

Oh, and RAM is much faster than constantly swapping to an SSD. I only have 4GB of RAM in this laptop, and my Commit Charge was nearly 5GB, and browsing was a bit... sluggish. Now it's rather snappy again, after a reboot.

(I also ordered an 8GB kit of RAM for it just a little bit ago. Good times!)

Swapping to ssd is faster but puts more stress on the ssd. use smart data to monitor the wear on the ssd and make sure your swap device support trim. Also some ssd writes are large blocks; this is important when writing many small blocks since that actually amplifies the actual writes. Not sure abuot window but most swapping devices are page driven (4k); so if your ssd only support large blocks (sometime as bad as 256K); those 4K sync writes are really expensive with regards to wear on the ssd device.

I'm surprised that people use Sleep or Hibernate, I'll power mine on when used and then shut it down, if you've got a SSD it doesn't take that long to boot.

My linux box (which I use once a day and goes into hibernate mode when not in use) hasn't leaked memory in 2 months. Of course it runs linux so that might be part of the reason for improve stability.

Hibernate on a computer with an SSD is also waste of space used by the Hibernate file.
Since an SSD equipped computer starts up as fast a computer comes up out hibernation it's useless with an SSD.

I disagree. There are several very good reason to hibernate. Two of them include as a 'safe guard' if you forget to turn the computer off. Second it preserve the state of your system (i.e, if you are working on a project or whatever). You argue that it is a waste to hibernate since you can restart the computer just as fast. The only 'waste' is a relatively small amount of space.

Oh please. Linux S3/4 states have their fair share of bugs. The most glaring being the fact that in S3 it sips way more power than the same Windows machine.

S3/S4 states preserves the workflow? For my home/work computer, I always set it to sleep when I go to bed. I haven't noticed any memory leaks in Windows 8 or newer.

Evidence ? Please make sure the evidence includes info on a 4.4 kernel.

So Ubuntu 16.04 is based on the 4.4 kernel. I searched the Ubuntu forums and came with these just on the first page.

Looks like some S5 power issues simply due to WoL. Windows does NOT have this problem.

Looks like you have to disable Nvidia drivers before sleep. Such a user friendly solution!

There's also a boatload more complaints about how 16.04 gets less battery life than a comparable Windows laptop. Which is totally believable because Linux ACPI and power management has always sucked compared to Windows. For my personal anecdote, I use Ubuntu 16.04.1 LTS (4.4.0-63) on a Thinkpad T430s. When in suspend, the battery drains about 10% a day. For comparison, I loaded Windows 10 (forgot build), and there was literally no battery drop after 1 day in sleep (this is with hybrid sleep disabled, because Linux by default doesn't support that).

 

[VirtualLarry]

Yeah, power-management under Linux really sucks. (See "Bay Trail bug")

 

[you2]

the title of one of the thread is; note after shutdown not after suspend. BTW Under windows 7 on one of my motherboards I had HUGE power drain after shutdown; the problem was that motherboard did not shutdown usb 3 port. They considered a feature but the bios had no method to disable that feature. Not sure if windows 10 would have the same issue; my fix was to replace the motherboard.

I used the bios to disable the powered USBs on my current laptop for that reason.

But this has nothing to do with the OS.
